. 'The invention relates to slub catcher and yarn guide.

One of the objects oi the invention Vis to provide a slub catcher particularly adapted for detecting slubs and other imperfections in roving V coming from a card tape condenser or other similar textile machine,

Another object of the invention is to provide a l-slub catcher of the above character so constructed as to permit the easy threading of roving therethrough.

- Anotherrobj'ect of the invention is to provide a slub catcher which'may be adjustable for dif- -ferent diameters of roving.

Another object of the invention is to provide axslub catcher of the above character so conrov- A" more speciiic object of the invention is to provide a slub catcher adapted to be used in place of the heretofore standardgtraverse wire guide rod on card tape condenser machines.,

With these and other objects in View, the invention consists of certain novel features of confcatcher embodying our invention and attached to 'the traverse bar of a card tape condenser machine; I

Figure 2 is a similar view but showing the parts thereof in different relation for threading roving or-similar yarn therethrough;

Figure 3 is asection view taken substantially "along line 3 3 showing roving with a slub thereon in a positionabout to be caught by the dejtecting portion of the slub catcher;

Figure 4 is a sectional view taken substantially through lines t--- of Figure 2 and showing the manner in which the device is attached to the vtraverse rod and the manner in which the two plates are slidably related to each other;

Figure 5 is a section View taken substantially along line 5--5 of Figure 1; y

Figure 6 is a section taken Substantially along line 6- 6 of Figure 2; and Figure 7 is an elevational view of a iragmental portion of one of the plates of the slub catcher shown in the above gures. n The guide and slub catcher which We provide is attached to the traverse bar of a card tape condenser and takes the place of the wire guide previously used. The device 'consists cfa pair of slotted"`plate's' slidable one on the other to cause 9 Claims.V (Cl. 28-70) slotted screw .2? the slots to align for receiving roving or be positioned out of line to lock the roving in desired position.

Referring to the drawings for a more detailed description of the invention, Ill designates generally a slub catcher embodying one form of our invention and comprises a member or plate ll which may be of any desired length and preferably made of a metal material. The plate I l (Fig. l) is provided with a plurality of equally Yspaced generally vertical slots I2 the walls of whichextend inwardly from the upper edge of the plate for a substantial distance and then open at right angles as at I3 to form a generally L- shaped slot. The end wall of the slot portion i3 is arcuate or semi-circular as at I5. The edges of the slots I2 may be rounded to provide a smooth surface against which the yarn or roving may engage. vOne end of the plate H is right angularly deiiected as at I6 (see Figure 5) so as to provide a support il for an adjustable stop I3 which in the present disclosure comprises a I9 which threadedly extends through the portion Il. A lock or jam nut 20 secures the screw I9 in adjusted position.

A second member or plate 2l oi substantially the length of the plate II but much narrower is mounted on the plate Il to have surface contact therewith while providing for relative longitudinal sliding movement. In the present instance this is accomplished by means of slotted openings 22, 22 there being two shown but any suitable number may be provided conditioned upon the length of the plate and the weight thereof. Stud fastenings 23 having a reduced threaded portion 2t are received through these slots 22 with the threaded portions extending through suitable openings in the plate Il, which receives jam nuts 25 to secure the studs to the plate I I securing the plates to each other to permit slidable relation therebetween. The plate 2l is provided with a plurality of equally spaced generally vertical slots y2li the edge walls of which extend inwardly'from the upper edge of the plate and with the bottom wall thereof rounded or semi-circular las at 2l and in register or in line with the bottom the walls of the bearing 28 move said plate slide 2i in one or the other direction relative to the plate II. As previously stated, there is an equal number of slots 25 and I2 so that in one position of the plates relative to each other the slots 25 will be in register with the vertical portion of slots I2. This location is determined by the stud engaging against the end wall 32 of the slots 22. In this position of the slots I2, 28 roving or like textile material may be threaded into the said slots I 2 and 26. Moving the handles 3l! in a counter-clockwise direction as seen in Figure 2 will slidably move the plate I2 to push the roving into the angular portion I3 of the slot I2 so that the wall 25 of slot 2t will be positioned in line with or overlap the walls I2 of slot I2. This will close the angular portion of the slot I2 at the wall 26 and capture the roving in the openings 33 thus formed by the portion I3 and the wall 25 of the slot I2. In order to provide the proper size opening 33 for a particular size roving, the plate 2l is angularly deflected as at 34 (Figure to provide a right angular abutment 35 in line to engage against the screw I9. Thus it will be seen that by the adjustment of the screw I9, the size of the opening 33 may be adjusted by overlapping of the walls I2' and 2l the required distance.

Tape condensing machines are usually provided with a traverse wire guide through which the roving passes to be guided on to the take-up spools. The slub catcher device of the present invention is substituted for the said usual traverse wire guide of a tape condensing machine and is attached to the traverse bar 36 thereof as b5" means of screw fastenings 3l'. Thus the slub catcher will be traversed in a manner similar to that of the said wire guide rod to guide the roving on to tal e-up spools, not shown.

The operation of the device has been given more or less in the detailed description of the parts thereof, and it is believed that it will sufce to state that when yarn is to be threaded into the combined guide and slub catcher, either handle 3E? is moved in the proper direction so as to register the slots 26 with the vertical portions of slots I2. The roving or yarn may now be dropped into the slot 25 and the handles 3E moved in the opposite direction so as to push and confine the roving into the openings 33. The size of these openings 33 will be adjusted in accordance with the diameter of the roving passing therethrough and any slub S (see Figure 3) or other imperfection of an enlarged nature in the roving will be locked and further tension on the roving from the take-up side of the device will break the roving. It will be apparent that if some portion of roving is of greater diameter or thickness than that of the size of openings 33, this portion of roving upon reaching opening 33 will lbe yblocked from passing through and broken as above de scribed.

It will now be apparent that the use of this device on card tape condensers and like machines will assure the making of a cleaner and more even yarn from a cleaner and more even roving off the cards. The slub catcher is adapted for use for wool or other bers carded and spun on the woolen system.
